INSULATED CONTAINER.

My ihvention relates to an insulated containerlfor transporting or storing ice cream or other soluble substance.

The object of my invention is to provide a container having air chambers in the wall and lid thereof formed from fibrous material as a non-conducting element co-acting with the air chambers.

A further object of my invention is to 1o provide a container of the kind described as a means ot reducing the weight over other containers with equal' capacity of contents. y

A still further object of my invention is to provide a manner of construction that will permit the use of the form and materials herein set forth to produce a structure of a shape disclosed Iin the drawings, the

bottom being integral with the side wall.

2o A. still further object of my invention is to provide a re-inforcing means for vthe corrugated sheets, whereby additional air cells are provided.

A still further object of my invention is to construct an inexpensive container that after once being used it may be discarded or considered non-refillable so far as a guarantee of suciency in strength is concerned. x

'llhese and other objects will hereinafter be more fully explained.

Referring to the drawings:

Fig. 2 is a top view, the lid being removed.

lFig. 3 is an enlarged sectional detail through the bottom, taken oh line AA in Fig. 2. 4o ig. d is a planV view of the lid, parts removed for convenience of illustration.v

Fig. 5 is an enlarged fragmentary sec# tional view through the lid, taken on line BB looking in the direction of the arrow.

`liig. 6 is a view of the corrugated mate. rial before being rolled in cylindrical form showing the V-shaped cuts along the bottom; Fig. 7 is an enlarged fragmentary sectional view taken on line CC in Fig. 1.

rlhe container herein disclosed is conf. structed of a plurality of corrugated sheets l, being made of wood fiber or the like. The corrugations being vertically positioned for the side wall. The bottom being formed by removing V-shaped portions asat D. The apex of theremaining portion intersect exterior sheets.l

'lhe lid 4c being made in the same manner except that the corrugations are transversely positioned to each other;` the edges thereof bein fpressed together and laterally extendlng i rming adange 5 to-t snugly over 'the top of the container.. Between the plies of the corrugated sheets is a plain sheet 6 attached iirmly to the corrugations b adhesive substance. A similar sheet is app ied to the exterior and interior of the container, the

exterior sheet connected to the corrugations by adhesive substance while the interior may be placed without connecting irmly by ad` The interior and exterior sheets when applied to the bottom function as a bonding material holding'the apex members rmly together.

lard or other like substancemay be preservedv and transported therein.

Such modifications may beeemployed as to the size, shape and manner of assembly,l *y I andthe materlals .employed -forming the sheets that are corrugated, and adhesive employedin the lamluation. i
